Re: Windows 8 won't boot through Gummiboot

I am pretty sure you will need a shared  EFI partition to use gummi to boot both operating systems.  I think I saw somewhere in the wiki that it's limited to only being able to boot systems on its own partition.

That's correct; gummiboot is limited to reading one partition, which means that any boot loader you want to launch from gummiboot (including your Linux kernel(s)) must be on the same partition as gummiboot itself.

Re: Windows 8 won't boot through Gummiboot

I am pretty sure you will need a shared  EFI partition to use gummi to boot both operating systems.  I think I saw somewhere in the wiki that it's limited to only being able to boot systems on its own partition.

That's correct; gummiboot is limited to reading one partition, which means that any boot loader you want to launch from gummiboot (including your Linux kernel(s)) must be on the same partition as gummiboot itself.

I am having the same issue here.
The relevant part of my partition scheme is:

sdc           119,2G 
├─sdc1 vfat     512M     --- arch's  /boot
├─sdc2 ext4      50G     --- arch's /
└─sdc3 ext4    68,8G    --- arch's /home
sdd           232,9G 
├─sdd1 ntfs     300M Recovery
├─sdd2 vfat      99M      --- windows 8 boot
├─sdd3          128M 
└─sdd4 ntfs   232,4G Windows

These are 2 GPT partitioned disks.
Does this mean that I have to copy files from /dev/sdd2 to /dev/sdc1 to make windows bootable from the gummiboot menu?

EDIT:

Yep, that worked! (although it doesn't seem like a very elegant solution.. )

Re: Windows 8 won't boot through Gummiboot

If you switch from gummiboot to GRUB, you can have separate partitions.  If you're content with gummiboot, that's your only choice.

FWIW, rEFInd can also boot from multiple GPT partitions.
